Category: Aliens

In the Season Two episode, 2.19 "One False Step", Daniel Jackson defined the word "alien" for Teal'c as referring "to anything characteristic of a very different place or culture. Anything really strange relative from our own perspective."

From our perspective, even humans transplanted to another world from Earth are "aliens". They are in a different place and have developed their own cultures. And then there are the really "alien" aliens, the ones some of us would define as "really strange".

They are all included here. The only "aliens" that you won't see are the ones who are called human beings and live on the planet called Earth. To our alien friends out there, we are the aliens and have been given the name by some to be Tau'ri, and by others, kindred.

Abydonians

Kasuf of Abydos

The Abydonians are descendants of those taken by the Goa'uld Ra from Ancient Egypt of Earth 10,000 years ago. They speak an ancient form of Egyptian called Abydonian. We meet the Abydonians in the movie Stargate and they became our first allies in the war against the Goa'uld.

Aliens of PJ2-445

Aliens of PJ2-445

The Aliens of PJ2-445 were encountered in the episode 2.19 "One False Step". As it turned out these "naked, white" aliens weren't really naked, but painted themselves with a material which hardened to protect and cover them. They appeared to live simply in adobe-like structures. They communicated mostly through body language, but they also sang in complex harmonies and had a symbiotic relationship with the plant life of the planet.

Amra Delegates

Amra Delegates

The Amra Delegates were a pair of bickering aliens escorted to the SGC by SG-5 to negotiate a trade agreement in the episode, 8.04 "Zero Hour".

Ancients

Ayiana of the Ancients

The Ancients are the builders of the Stargate. They were a race of humans who lived millenia before those on Earth. The group known as "The Others" are the Ascended Beings of the Ancients. Those Ancients who did not ascend with The Others died of a plague that swept their galaxy a very long time ago. The Ancients are the "ancient ones" whose language evolved into Latin and Dr. Daniel Jackson identified them as those who were the builders of the roads spoken of in ancient Earth writings.

Argosians

Alekos of Argos

The Argosians were originally placed on their planet Argos as a genetic experiment by the Goa'uld Pelops. Pelops used nanotechnology to accelerate their growth and limit their lives to a mere one hundred days. The SGC destroyed the technology and the Argosians were given the opportunity to live their lives to the fullest, living years instead of days. We meet the Argosians in the episode, 1.09 "Brief Candle".

Ascended Beings

Daniel Jackson as an Ascended Being

The Ascended Beings exist as a form of energy on a higher plane. They can shape themselves into a form familiar with those with whom they interact, much like Daniel Jackson did for his friend Jack O'Neill in the episode 6.06 "Abyss". Ascended Beings are introduced in the episode 3.20 "Maternal Instinct".

Aschen

Molum of the Aschen

The Aschen were first introduced in the "future" episode 4.16 "2010". They are a highly developed people and considered very patient, but under their calm exterior lies the mind of those who would slowly and methodically kill an entire world's population in order to conquer it.

Asgard

Thor of the Asgard

The Asgard were first met by Dr. Daniel Jackson and Captain Samantha Carter on the planet Cimmeria in the episode 2.06 "Thor's Chariot". They are called the "Roswell greys" by Carter. The Asgard aligned themselves into a group of four races to share knowledge and protection. The other three races were the Ancients, the Nox, and the Furling.

Beings of Oannes

Nem of Oannes

The Beings of Oannes are humanoid-fish beings who can breathe comfortably in either water or on land. Their species visited Earth during the time of the Babylonian empire in an attempt to overthrow a Goa'uld named Belus. The Beings of Oannes are introduced in the episode 1.13 "Fire And Water".

Crystaline Entities

Crystaline Entities of P3X-562

Crystaline Entities are energy beings which store themselves in blue crystaline structures and are able to mimic any shape, including that of a human being. They have the ability to read thoughts. The Goa'uld nearly completely wiped them out when one of them attempted to protect itself with electricity, killing the Jaffa who approached it. The Jaffa gathered them together and fired upon them with their staff weapons, leaving them for dead. We first meet the Crystaline Entities in the episode 1.07 "Cold Lazarus".

Enkarans

Eliam of the Enkarans

The Enkarans are humans who have adapted to a rare planetary condition hard to match. They are extremely sensitive the Earth's level of UV radiation and this sensitivity causes them to first go blind and then to die. Their oddly colored eyes give the Enkarans their distinctive difference in appearance from humans of Earth. We first hear of the Enkarans in the episode 4.07 "Watergate" and meet them in the episode 4.09 "Scorched Earth".

Eurondans

Alar of the Eurondans

The Eurondans are humans who divided their world Euronda into two groups: those who followed racial purity and those who did not. The SGC was contacted by Alar, the leader of the side which wished to totally wipe out the Breeders. SG-1 did not discover this aspect of their relationship early on and as a consequence allied with those who would destroy those who were "not like us". We meet Alar and his genocidal faction in the episode 4.02 "The Other Side".

Furling

We have never met the Furling

The Furling have been mentioned as being a fourth race in an alliance with the Ancients, the Asgard, and the Nox. We have never met the Furling and don't know what they look like or even if they still exist. We first hear of the Furling in the episode 2.16 "The Fifth Race".

Foothold Aliens

Foothold Alien

The actual name of this alien species has not yet been revealed, so they are referred to as the Foothold Aliens. They are believed to be from P3X-118. They were able to infiltrate the SGC by posing as members of SG-6 in the episode, 3.14 "Foothold".

Gadmeer

Gadmeer

The Gadmeer were an advanced and peaceful civilization overrun by a great military power. In order to preserve their 10,000-year-old civilization, they built a large terraforming ship which would transform planet P5S-381 into a sulfur-based ecosystem suitable to sustain their transplanted lifeforms. We learn of the Gadmeer in the episode 4.09 "Scorched Earth".

Goa'uld

Goa'uld Hathor holding a Goa'uld symbiote

The Goa'uld are parasitic creatures who have evolved into highly intelligent beings. They require a host, such as a human being, to fully use their intelligence. Their first hosts were of the Unas species, but eventually the Goa'uld found that human beings were preferable. Through the stargate network, the Goa'uld spread across galaxies and transplated humans from Earth to various planets suitable for humans to thrive. Humans were "harvested" to further the Goa'uld's race. Many of the Goa'uld who established themselves on Earth 10,000 years ago took on the persona of the mythological gods and goddesses. The name "Goa'uld" was first used in the series pilot, 1.01-1.02 "Children Of The Gods", but the parasitic nature of the species was introduced in the original film through the person of Ra.

Hankans

Cassandra of Hanka

Every person on the planet Hanka was killed by the Goa'uld Nirrti, except for a little girl named Cassandra. She was taken to Earth and nursed back to health, then adopted by the SGC's Dr. Janet Fraiser, in the episode, 1.15 "Singularity".

Hebridians

Aden Corso of Hebridan

The Hebridians are humans who were taken from Earth's Celtic culture. Their world was dominated by the Goa'uld until the Serrakin freed them. From that time on, the two species have lived together, some of them even marrying. The Hebridians were first introduced in the episode, 6.18 "Forsaken".

Jaffa

Jaffa with his pouch exposed

The Jaffa are genetically altered humans of Earth, designed to carry a Goa'uld symbiote in an abdominal pouch. By incubating the larval Goa'uld, Jaffa are given extended lives (some beyond 135 years), formidable strength, and an inhanced immune system with shortened healing periods. Because of these benefits, some Jaffa become warriors in service to a Goa'uld System Lord. Other Jaffa service the Goa'uld in their temples. The Jaffa were introduced in the series pilot, 1.01-1.02 "Children Of The Gods".

Kelownans

Jonas Quinn of the Kelownans

The Kelownans are a race of humans living on the planet Kelowna. Jonas Quinn is one of the most notable of these people, having become a member of SG-1 for one year. Jonas has a physiology which permits him to be a quick study and retain information like one with a photographic memory. He also has other physiological differences which gained the interest of Nirrti and Anubis both. It is not clear if these advances in physiology were specific to Jonas alone or if they were shared by other Kelownans. We meet the Kelownans in the episode 5.21 "Meridian". It is on this planet that Daniel Jackson was exposed to the lethal dose of radiation which killed him. In Season Seven, the planet was renamed Langara in an attempt to recognize the uniting of the three major nations of the world: Kelowna, Andari, and Terania.

Nomads of Vis Uban

Arrom of Vis Uban

The Nomads of Vis Uban lived among the ruins of a city built by the Ancients. The place name Vis Uban means "place of great power". These are the people who found Daniel Jackson when he returned to human form after being one of the Ascended. This culture was introduced in the episode, 7.01 "Fallen Part 1".

Nox

Lya of the Nox

The Nox were introduced in the episode 1.08 "The Nox". They are an advanced race who are pacifists. They possess great mental powers, including the ability to transport themselves, cloak themselves and others, and activate the stargate without the use of a DHD.

People of P3X-367

Alebran of P3X-367

The People of P3X-367 were the victims of the Goa'uld System Lord Nirrti in her attempt to genetically engineer the perfect human host, called a hok'tar. They were successful at stopping the experimentation, but not before many of their people died, in the episode, 6.16 "Metamorphosis".

People of P4S-237

Ellori of P4S-237

The People of P4S-237 lived in the hope of ancient prophecy which foretold of their eventual freedom from the enslavement of the Goa'uld. Their planet was controlled by the Goa'uld System Lord Mot who was collecting a tribute of naquadah, seemingly for his lord, Ba'al, but actually for his own benefit in his plans to overthrow Ba'al. The SGC came at a time when Mot visited and with their help, the people were able to gain their freedom, in the episode, 6.21 "Prophecy".

People of Talthus

Pharrin of Talthus

The People of Talthus built three cryosleep ships to escape from the sun flare triggered by the gravitational pull of a dark star which passed near it. The people were on their several-hundred-year trip to another planet called Ardena when the ship Stromos crashed on a planet which SG-1 visited, in the episode, 7.06 "Lifeboat".

People of the Land of Light

Tuplo of the Land of Light

The People of the Land of Light are humans from Earth's Minoan civilization. They are a gentle people who live in a land of plenty. We first meet them in the episode 1.05 "The Broca Divide" when we helped them overcome a medical condition which caused many of their people to mutate into primitives. Grateful for our help in curing "The Touched", they formed an alliance with Earth and have offered their world as sanctuary for any displaced peoples we might encounter in our travels.

Rand Protectorate

Commander Gareth of the Rand Protectorate

The Rand Protectorate was a country on an unspecified planet introduced in the episode, 8.05 "Icon". Upon SG-1's arrival through the stargate, the Rand Protectorate and the second country of the planet, the Caledonian Federation, ended up firing their missiles at each other because a religious zealot named Soren caused civil unrest, claiming that the stargate's activatation supported his religious beliefs that the gods would return and reward the faithful. All three parties in this war were devasted in short order, but the Rand Protectorate, along with the SGC, led the way to rebuilding the societies.

Replicators

First Generation Replicators

The Replicators are artificial life forms which are built on nanotechnology. At first, they were created by an android named Reese as toys, but soon they became independent with the highest priority being survival through replication, hence their name. An attempt by the Asgard to stop their devouring of technologically advanced civilizations (they used the technology to create more of themselves) unintentionally led the Replicators to evolve from bug-like to humanoid. The Human Form Replicators hold the intelligence capability of their creator, Reese. The Replicators were introduced in the episode 3.22 "Nemesis" and the Human Form Replicators, in the episode 6.12 "Unnatural Selection".

Serrakin

Warrick of the Serrakin

The Serrakin are a technologically advanced race of humanoids. They are genetically compatible with humans and many of their race have intermarried with the humans of Hebridan (Hebridians whose ancestors they freed from Goa'uld enslavement). The Serrakin were introduced in the episode 6.18 "Forsaken".

Tagreans

Ashwan of Tagrea

The Tagreans were a people without a past. Their ancestors overthrew their Goa'uld oppressor Heru'ur and buried their stargate in defiance. They also destroyed all records of Heru'ur's enslavement of their people. SG-1 and the crew of the Prometheus helped them find their stargate and uncover their past in the episode, 6.20 "Memento".

Unas

Chaka of the Unas

According to a theory developed by Drs. Daniel Jackson and Robert Rothman, the Unas evolved on the same planet as the Goa'uld and were, therefore, the first hosts to the symbiotes. Eventually, however, the Goa'uld preferred to take human beings as hosts because their bodies were more easily maintained. Because of their physical strength, however, the Unas became slaves of the Goa'uld, primarily used to mine the precious mineral naquadah upon which the Goa'uld's technology depends. The Unas were introduced in the episode 1.10 "Thor's Hammer".
